Use the above animation on echalk to help you to learn the learning objectives below (M11). Only when you feel you have mastered a learning objective can you move on to the next.
In the animation:
Read the instructions.
Using some of the learning objectives below to attempt to build a number of atoms with all 3 types of subatomic particles in the correct place in the atom.
You should also work out what information the mass number and atomic number give you about the structure of an atom.
Once you have completed an atom, click on the "choose an element" tab, find your element that you have made the atom of and find a link between the atom and the information about the element in the periodic table.
Learning objectives (M19)
know the structure of an atom in terms of the positions, relative masses and relative charges of sub-atomic particles.
know what is meant by the terms atomic number, mass number, isotopes and relative atomic mass (Ar)
Learning objective (M11)
Know the structure
Recall that electrons move around or orbit around it in shells or energy levels
Know the relative charge and relative mass of a proton, electron and neutron
Know what the atomic number is and what information it gives
Know what the mass number is and what information it gives
Know how to calculate the number of protons, neutrons and electrons in an atom when the atomic number and mass number are given
Recall the number of electrons that can orbit in each energy level
Be able to draw an atom of the first 20 elements in the periodic table showing all the electrons.
Once you feel you have mastered all of them, go onto handout 1c and work through page 1 and the top of page 2.
Look at the sample calculation at the top of page 3 and complete the table below it.
Electron arrangement and the periodic table
Read this section on pages 3 and 4 in the handout and complete the task on page 4 (the table). Once you have completed the table answer the following questions - you can also use echalk: "electronic structure:visual database"
What information does the group number give about the atoms in that group?
What information does the period number give about the atoms in that group?

Use the above animation on echalk to help you to learn the learning objectives below (M11). Only when you feel you have mastered a learning objective can you move on to the next.
In the animation:
Once you feel you have mastered all of them, go onto handout 1c and work through page 1 and the top of page 2.
Isotopes
When you get to isotopes on page 2 of the handout, go to

Now complete the table on page 2.
Relative atomic mass
Look at the sample calculation at the top of page 3 and complete the table below it.
Electron arrangement and the periodic table
Read this section on pages 3 and 4 in the handout and complete the task on page 4 (the table). Once you have completed the table answer the following questions - you can also use echalk: "electronic structure:visual database"
- What information does the group number give about the atoms in that group?
